| 15:44.03 | r00t-Ed | hello |
| 15:49.05 | drath | r00t-Ed: Hi |
| 15:50.58 | r00t-Ed | hi drath, i wonder if you have a minute to ask you a couple of things about the xscale jtag |
| 15:55.16 | drath | heh, i wont guarantee any response times (i'm currently at work), but yeah, feel free to ask |
| 15:56.26 | r00t-Ed | ok, is not that important, i am at work too, i grabbed a device that has an ixp425 and flash, it boots fine with redboot |
| 15:57.04 | r00t-Ed | i wanted to actually backup the flash prior to start messing witht the image on the flash |
| 15:57.42 | r00t-Ed | so i has the 20 pins jtag port, i see that it is common for the xscale base boards |
| 15:58.07 | *** join/#openjtag prpplague (n=dave@mail.americanmicrosystems.com) |
| 15:59.02 | r00t-Ed | i build the cable, but now i am looking for a software that will allow me to do the flash backup |
| 15:59.48 | r00t-Ed | we have a bdi2000, but i just realized that it is for a different target |
| 16:06.11 | r00t-Ed | i found something about the jtag tool for linux |
| 16:06.21 | r00t-Ed | but wonder if there is a better way ? |
| 16:06.50 | drath | if you just want to backup the flash, and possibly restore it at a later point, the openwince jtag tool should be fine for you |
| 16:06.53 | r00t-Ed | can you backup stuff from redboot ? i see that you can load stuff from the tftp |
| 16:07.19 | drath | sorry, i haven't used redboot a lot |
| 16:07.45 | r00t-Ed | ok me neither.. openwince, thanks i will look that up |
| 16:07.49 | drath | and in any case, you wont be able to restore your flash, once you've (possibly) broken redboot ;) |
| 16:09.25 | r00t-Ed | i know, i was tempted to update the redboot, this is version 1.9 i found that they are in 2.5 or soemthing |
| 16:09.49 | r00t-Ed | and it is easy to do,i just want to backup the flash before i start playing with it |
| 16:10.40 | drath | be prepared that using the openwince jtag tools is going to take quite some time |
| 16:11.19 | r00t-Ed | i see, yes, i saw a post (that is how i got here) about 45 mins for 256kb |
| 16:11.28 | r00t-Ed | this flash is 16mb |
| 16:11.40 | r00t-Ed | there must bet a faster/better way i think |
| 16:12.07 | drath | well, there's xscale support available for the bdi2000, but you've got to buy a separate license for each target family |
| 16:12.55 | drath | alternatively there's the OpenOCD |
| 16:13.04 | r00t-Ed | yes, i found that out very quickly, the one we have is for some ppc architecture |
| 16:14.46 | drath | people have successfully used the openocd to debug and flash ixp42x based devices |
| 16:15.29 | drath | but using the openocd (or the bdi2000 for that matter) places some additional requirements on the JTAG interface, and the target's reset circuit |
| 16:17.39 | r00t-Ed | let me try that jtag from openwince, see if i can query the device and stuff |
| 16:18.22 | drath | allright, i'm on my way home now, bye |
| 16:18.32 | r00t-Ed | bye thanks |
